The 1983-S Proof Set invites scrutiny, because of the possibility of finding an "S"-less Dime.

Each set contained five coins: One example each of the Lincoln Cent, Jefferson Nickel, Roosevelt Dime, Washington Quarter, and Kennedy Half Dollar.

About the sets: All coins in the 1983-S Proof Set were intended to have a Cameo or Deep Cameo Finish.

An unknown number of 1983-S Dimes were struck without a mintmark. This error occurred just as it had in the past, when the Philadelphia Mint failed to add a mintmark to a Proof die prior to shipment to the San Francisco Mint. The exact mintage is unknown, nor has the Mint provided an estimated mintage. However, the life of a Proof die is about 3,000 – 3,500 coins, so it would be safe to say that less than 3,500 coins exist.

Mintage: 3,138,765 sets

Original packaging: In 1983, the Mint reverted to a packaging system very close to that of 1968. The coins of the 1983-S Proof Set were placed in individual holes in a black plastic insert, then sealed in a two-piece, clear plastic case. The case was then inserted into a protective outer cover, consisting of blue cardboard imprinted with the words: "United States Proof Set • 1983."
